In a peer-reviewed clinical trial published in SKINmed Journal, researchers compared Rosemary oil directly to Minoxidil 2% — one of the most widely used hair loss treatments in the world. After 6 months both groups showed significant increases in hair count with no statistically significant difference between them. The Rosemary group reported fewer side effects — less scalp irritation, less itching, no dependency. Regenx is built around this research, combining Rosemary with eight more clinically studied actives including Saw Palmetto, Redensyl, Aminexil and AnaGain — each targeting a different stage of the hair loss cycle.
